+	---help---
+	    Note: Non-standard SocketCAN sockopt, but this options helps us in
+	    real-time use cases.
+
+		When the CAN_RAW_TX_DEADLINE sockopt is enabled. The user can send
+		CAN frames using sendmsg() function and add a deadline timespec
+		value in the CMSG data. When the deadline has been passed and the
+		CAN frame is still in the HW TX mailbox then the CAN driver will
+		discard the CAN frame automatically.

+	depends on NET_CAN_RAW_TX_DEADLINE
+	---help---
+		Some applications may not use the NET_CAN_RAW_TX_DEADLINE flag.
+		By default their deadline becomes 0 which means it becomes infinite.
+		This would mean that packets from applications without the
+		NET_CAN_RAW_TX_DEADLINE flag, can block the TX mailboxes forever.
+		This config can set the default deadline when no deadline has been
+		given.
+
+config NET_CAN_RAW_FILTER_MAX
+	int "CAN_RAW_FILTER max filter count"

+	depends on NET_CAN_SOCK_OPTS

+	depends on SCHED_WORKQUEUE
+	select WQUEUE_NOTIFIER
+	---help---
+		Enable building of CAN notifier logic that will execute a worker
+		function on the low priority work queue when read-ahead data
+		is available or when a CAN connection is lost.  This is is a general
+		purpose notifier, but was developed specifically to support poll()
+		logic where the poll must wait for these events.
